sÎ Validates (or generates) a device name for instance.
If device is not set, it will generate a unique device appropriate
for the instance. It uses the root_device_name (if provided) and
the list of used devices to find valid device names. If the device
name is valid but applicable to a different backend (for example
/dev/vdc is specified but the backend uses /dev/xvdc), the device
name will be converted to the appropriate format.
